We could in theory have such a switch but I am not a fan of the idea
since objects in the database can depend on objects in the extension,
objects which might not exist in the newer version of the extension
making the dump impossible to load.
We would also lose other things such as permissions on the extension
objects, but that might be something the users are willing to accept.
If we are doing something like this I would rather have a switch for
attempting to upgrade all extension to the latest version after upgrade
and let the users get the potential errors there.
